Abstract
A security trimming system disclosed herein uses intelligent caching of the security trimming information received from a security datastore. The security trimming system uses an access cache to store the security trimming information received from the access datastore together with other parameters associated with such security trimming information. Subsequently, in responding to a request for the security trimming information, the security trimming system uses the cached value of the security trimming information together with the other associated parameters to determine a response to the request from the content providers. In one implementation, if the other parameters associated with a particular security trimming information imply that the security trimming information in the cache is still valid, the cached security trimming information is used in the request response. Otherwise, a new request is sent to the security datastore for an updated value of the security trimming information.
